About Knox
Knox runs the largest Federal and DoW managed cloud, building and operating secure cloud and AI environments that support the U.S. government’s most critical missions — from national security and public safety to essential public services. Our customers rely on Knox to deploy production systems that meet the highest standards for security, reliability, and compliance.
Work at Knox is high-impact and purpose-driven. The problems we solve are high-stakes, the expectations are high, and the results are visible. Speed, rigor, and trust matter here - because the environments we secure cannot fail. Your contributions are visible, your expertise is relied upon, and the impact of your work is immediate and measurable. We operate at federal scale, securing some of the most sensitive government environments in the country - because the systems we build must perform without fail.
Most companies run a security team and a network team separately. We don’t. At Knox one team watches everything — performance, availability and security — out of the same queue. You see the whole picture, and a problem never sits with the wrong team while the clock runs. It is a better way to work and a much faster way to learn.
